BOAT-DETACHING APPARATUS.

Specification of Letters Patent.

Application filed February 7, 1912.

Patented Mar. 26, 1912.

Serial No. 676,382.

Ohio, have invented certain new and useful Improvements in Boat-Detaching Apparatus, of which the following is a specification.

This invention relates to boat detaching apparatus for suspending a boat from the davits, and is designed especially for readily releasing both ends of a boat simultaneously but will safely carry the same until the apparatus is manipulated.

The main object of the invention is to provide a practical apparatus of the above charact-er, which is positive and quick in action and can be easily manipulated by a person within the boat operating a lever.

With the above and other objects in view as will be understood, the invention consists in certain combinations and arrangements of the parts hereinafter described, and the novel features thereof will be distinctly pointed out in the appended claims.

For a full understanding of the invention, reference will be had to the accompanying drawings illustrating a preferred embodiment thereof, and in the drawings like characters of reference indicate corresponding parts. s.

Figure l is a side elevation illustrating my invention applied to a boat, parts of the boat being broken away to more clearly show the apparatus, Fig. ,2 is a sectional plan View taken on line 22 Fig. 1, Fig. 3 is a perspective view of the rocking shaft, Fig. 4 is a perspective view, on an enlarged scale, of one of the releasing hooks, Fig. 5 is a side elevation of Fig. 4, certain parts being broken away to better show the construct-ion, and Fig. 6 is a perspective view of the cam.

Referring to the drawings, 1 represents an ordinary life boat provided at each end with the usual tanks 2 and 3 and having a transverse seat 4. Each end of the boat is provided with a shackle 5 and is suspended from a pair of blocks 6 and 7 the upper ones of which are attached to the davits indicated at 8, and the lower or fall blocks carry the releasing hooks hereinafter described, which engage said shackles. The upper and lower blocks of each pair are connected together by a rope 9 for raising and lowering the boat in the usual manner.

Each releasing hook comprises a bar 10 of flat material to the lower end of which is hingedly connected as at 11, a plate 12 having at its free end a narrower portion or tongue 13 forming shoulders 14 therewith. The plate 12 is normally held at an acute angle with the front side of the bar 10 by means of a stirrup member 15, which is pivotally connected to the outer side of the bar as shown at 16 and engages the tongue 13 of said plate. Between the bar 10 and the plate 12 and engaging the inner sides thereof above the pivot point 11, is hung the shackle 5, which is preferably secured to the boat by means of a removable bolt 17 passing through the eyes 18 of the shackle.

In order to prevent accidental disengage ment of the stirrup member 15 from the tongue 13 and thereby release the plate 12, the stirrup member is provided with an upwardly projecting arm 19 bifurcated at its upper end for receiving the outer end of a locking lever 20 which is pivotally connected thereto at 21. The locking lever passes loosely through an elongated slot 22 formed in the bar 10 and is provided at its inner end with a suitable handle 23. The under edge of the locking lever is recessed at a suitable point as indicated at 24: for engaging the lower edge of the slot 22, and as a further means of safety a latch plate 25 pivotally connected to the bar 10 at 26 is adapted to engage the upper edge of the locking lever 20 and be secured in looking position by means of a pin 27 passing through alining openings in the latch plate and the bar 10, whereby the locking lever is securely held against upward displacement. The pin 27 is preferably connected to the bar 10 by means of a string or small chain 28.

The upper end of each bar 10 is provided with an opening 29 for receiving the usual depending eye member 30 of each fallblock 7.

In order that the releasing hooks may be operated in unison, a suitable cam 31 fixed to a transverse spindle 32 is pivotally mounted between a pair of bearings 33 which are fastened to the inner side of each bar 10, and said cams enga e the under curved edge 34 of the locking lever 20. Projecting rearwardly at a right angle from each spindle 32 is an arm 35 which terminates in a hook 36.

Depending from each of the hooks 36 is a chain 37 which passes under a suitable sheave 38 fixed to the boat at the bow and stern respectively as at 39 and 10. The chains 37 then pass preferably through curved tubes 41 and 42 secured to the inner sides of the boat by means of clips 48, and

the free ends of the chains are connected to oppositely extending arms 14 and 15 of a rocking shaft 46. The rocking shaft is preferably constructed of a square bar, having turned therein journals 4L7 which are mount- ,ed in brackets 48 fixed to the under side of the transverse seat 4 of the boat. Rigidly secured to the rocking shaft and extending,

forwardly thereof is a stub lever 49, to

which is fitted a removable handle 50 for rotating the rocking shaft to operate both of the cams 31 at the same time.

The operation of the apparatus is as follows: Assuming that the boat is suspended: and the parts are as shown in Fig. 1 and it is desired to lower the boat and detach it The pins 27 are first removed, the boat lowered in the usual man' from the davits.

ner, and then by pulling upwardly on the handle 50, the cams 81 will raise the locking levers 2O simultaneously and thereby disengage the stirrup members 15 from the tongues 13 of the inclined plates 12, which permits the shackles 5 to fall from the releasing hooks and eachend of the boat is de tached simultaneously.

that the chains 37 slide off the hooks 36 and the boat is entirely detached from the releasing hooks.

It is to be understood that slight changes in the details of construction and combina tion and arrangement of the parts may beresorted to within the scope of the claims.

Having fully described my invent-ion what- I claim is- 1. In a boat detaching apparatus, the combination of a bar, a plate hingedly connected to the bar, a stirrup member pivoted to the bar for holding the plate in an angular position wit-h relation to the bar, means interposed between the bar and the plate for nected to the bar, a stirrup member pivoted,

to the bar for holding the plate in an angular position with relation to the bar, and means interposed between the bar and the plate for supporting a weight, a locking lever pivoted to the stirrup member for engaging said bar to lock the stirrup member in normal posltlon, and a cam fa forcing At the same time that the cams 31 have rotated sufficiently to disengage the stirrup members from the in, clined plates, the arms 35 are so inclined the locking lever out of locking engagement with the bar and disengaging the stirrup member from the plate, substantially as described.
